摘要
本文对湘南桂阳松木圩下石炭统石磴子组的岩性、原生沉积构造、结构、生物组合特征、沉积环境条件等进行了初步分析研究,并据此,从时间上将该组划分为6个沉积相带。用层控的观点,对该组的含矿性(Cu,Pb,Zn)作了初步分析,提出今后在该区进行找矿工作中应注意的地段。
Based on the primary study of Shidengzi formation (lower carboniferous) in Songmuxu, Guiyang, South Hunan, the profile is divided into 20 beds and 6 vertical facies zones, according to their lithology and paleontology. These beds and zones can be correlated with neighboured area properly. Based on their lithological characters, such as their structures, textures, mineral constituents, ore-bearing grades and also on their sedimentary cycle, the author anticipates that the lower part of the concerned formation, including the upper part of Liujiatang formation, is the favourable section for the further geological pro- specting in this region.
